|

* Function: H5FD__supports_swmr_test()
|
||
*
|
||
* Purpose: Determines if a VFD supports SWMR.
|
||
*
|
||
* The function determines SWMR support by inspecting the
|
||
* HDF5_DRIVER environment variable, not by checking the
|
||
* VFD feature flags (which do not exist until the driver
|
||
* is instantiated).
|
||
*
|
||
* See test/Makefile.am for a list of the VFD strings.
|
||
*
|
||
* This function is only intended for use in the test code.
|
||
*
|
||
* Return: TRUE (1) if the VFD supports SWMR I/O or vfd_name is
|
||
* NULL or the empty string (which implies the default VFD).
|
||
*
|
||
* FALSE (0) if it does not
|
||
*
|
||
* This function cannot fail at this time so there is no
|
||
* error return value.
